“Nevada’s preservation backlog is estimated to be $2.1 billion,” Darrell Armuth, board member of the Nevada Highway Users Coalition, said in a statement. “To preserve the existing highway system, the state will need to immediately increase funding by $285 million for the next 12 years.”

The only city worse than Reno among midsize cities was Antioch, Calif., where 64 percent of roads are in poor condition and drivers pay an extra $793 because of it.

Just behind Reno were Santa Rosa, Calif., where 51 percent of roads are poor; and Trenton, N.J. and Hemet, Calif., at 48 percent each.

Among the largest cities, the four worst are in California — Los Angeles-Long Beach-Santa Ana, 64 percent poor; San Francisco-Oakland, 60 percent; San Jose, 56 percent; and San Diego, 55 percent.

Armuth said a lack of funding threatens the conditions of the nation’s roads and highways.

“Without a significant boost in transportation funding at the federal, state and local level, conditions will continue to deteriorate, drivers will continue to pay the price and our economy will suffer,” he said.
